To all whom t may concern: 1

Be it known" that I, SAMUEL ROBINSON, a citizen ofthe `United States, and a resident of v-White Plains, in the county of Westchester and State of New York have invented fav new and Improved Windshield Cleaner, of which the following vis a full, clear, Vand exact description. Y v Thisinvention relates to improvements inwind shield cleaners, an object of the inopthe outside of a wind Shield, so that the driver of a car may clearly see the road ahead when driving in inclement weather.

A further object is to provide a device of this character which is slidably mounted on a wind shield and to provide improved means for oscillating-the wiper.

A still further object is to providea wind shield cleaner; which will be simple and practical in construction, durable and o cient in use, and comparatively mexpensrve to manufacture.

With these andother objects in view, the invention consists in certaln novel features of construction and combinationsl and arrangements 'of parts as willbe more fully hereinafter described and pointed out in the claims.

In the accompanying drawings Figure 1 is a 4rspeetive view illustrating my improved wind shield cleaner in applied posltlon;

Figure 2 is a view in section on the staggered line 2-2 of Figure 1; and

lgure 3 is a view in sectionfon the line 3 3 of Figure 1, with parts broken away for clearness.

Referring in detail to represents an automobile wlth a wind shield such a frame .3.

The actuating mechanism of my improved win`d shield cleaner is enclosed in a rectangular box orcasing d. A bracket 5 secured athene end to the under face of the box 1 includes a hook-shaped portion 6, fitting over the upper frame bar of the wind the drawings, 1 which is provided as 2, mounted shield and supporting the box on the inside S of the wind shield lso 'that it is protected from the weather.

An externally threaded bearing sleeve through the outer Wall is locked in place by a pair The sleeve provides mount of the box/1 'and of nuts 8 and 9.

, a conventional ing for a shaft 10. A bevelled pinion 11 is Carried by the innerend of the shaft. A wiper carrying bar 12 is rigidly coupled at one end to the outer end of the shaft and carries any suitable form of wiper Such as 13.l The wi r 13 is maintained against the outer face o the wind shield by a coiledY expanslon sprin 14 located -around the shaft 10; :between t e inner end of the bearing sleeve 7 and a gasket or collar 15 on the shaft.

Any approved vmeans of coupling the arm 12 to the shaft l0 may be employed. I have illustrated a block 16 fixed to the enter end of the shaft 10 and bored to receive the outer end of therod 13, which is secured in place 1n the block by a set screw such as 17. 1

s1milar screw may be used to lock the bracket 5 against sliding movement on the up er frame bar of the shield.`

t will be a parent that in order to wipe the moisture om the outside of the wind shield, it will be necessary to impart an intermittent rotary motion to the shaft l0. This motion of the shaft will oscillate the arm 12 and move the wi er 13 backl and forth over the outer face o the wind shield.

I have illustrated one ractical andA simple means of imparting the esired motion to the shaft 10. Y is means comprises a shaft 18, journaled in the side wall carrying a pair of mutilated bevelled 19 meshing intermittently with the bevelled pin 11 to impart an intermittent rotary mo tion in opposite directions to the shaft 10. The shaft 18 may be connected by a wire such as 20 to any suitable motor (iot shown) for driving the same. circuit closing mechanism 21 in the form of push button construction secured in a convenient position to the steering collar 22 of the automobile and controlling the circuit which operates the shaft 18.

From the foregoing description it will be apparent that by merely pushing the button 21 to close the circuit, the shaft 18 will be rotated. The mutilated gear wheel 17 will mesh with the pinion 11 and rotate the shaft 1() intermittently in .o posite directions. ince the rod 12 is rigi 1y coupled to the shaft 18, this movement of the shaft will swing the wiper 13 back and forth over the outer face of the wind shield edectively cleansing the same.

As illustrated in Figure 3 the not only serves as a means for urging the of the box 4:, and

gears I have i ustrated a spring 1li rio wiper into engagement with the wind shield,

but as a means for urging the pinionll into engagement withf-'the mutilated gears 19. The tension of the spring 14 may be varied as the occasion requires by longitudinal'adjustment to the sleeve Z through the medium of the locking nuts 9.

Although I have illustrated one of'the preferred embodiments of my invention, it will be'apparent that various slight changes and alterations might be made in the general form and arrangement of the parts described without departing from the invention, and .hence I Ado not wish to limit myself to the precise details set forth, but shall consider myselr` at liberty to make such slight changes and alterations as fairly fall within the spirit and-scope of the appended claims.

I claim:

1. A windshield wiper comprising a easing having means whereby the same may' be` secured toa windshield, a sleeve extended into the casing','a-shat'rotatably extended through said sleeve and having one end provided -with a power transmitting member, a wiper connected to the other end of said shaft, operating means arranged within the casing and associated with said power transmitting` member, and a coiled spring confined between said sleevel and said power` transmitting member for urging the power transmitting member into engagement with the operating means andl for urging said wiper into contact with the Windshield.

'2. The construction set forth'in'claim 1, and nuts threaded on said sleeve and engaging opposite sides of said casing whereby to hold the sleeve in an adjusted position, said sleevev being `adjustable longitudinally for varying the tension of said s rin SAMUEL R BiisoN.
